RlMMING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 742,086, dated October 20, 1 903.

' Application filed m 15, 1902. Serial No. 115,678. (No model.)

' a citizen of the United States, and a resident of hubs.

Galion, in the county of Crawford and State of Ohio, have invented a new and Improved Rimming-Machine, of which the following is afull, clear, and exact description.

This invention relates to an apparatus for applying the rims or fellies to wheels, the spokes having been The machine embodies a saw for trimming the ends of the rim-sections, so as to cause them to fit properly with respect to' each other, and a hammer serving to drive the rims into the spokes, together with such auxiliary devices as the means for holding the wheelhub during these operations, for operating the hammer and saw, and the devices for mounting and adjusting the various operative parts.

This specification is an exact description of one example of my invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the invention. Fig.2 is a plan view thereof. Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. 4 is a section on the line 4 4 of Fig. 2, and Fig. 5 is a section on the line 5 5 of Fig. 1.

indicates the frame or base of the machine, on the table of which is mounted at one end the head-stock 11 and at the other end the carriage 12, which embodies the devices for holding the Wheel. .The carriage has two racks 14 connected therewith, (see the dotted lines in Fig. 1,) and these racks extend to the right from the carriage and are meshed with pinions 15, to the shaft of which is attached a hand-wheel l6, facilitating the rotation of the shaft.- By these means the carriage 12 may be moved on the frame or base 10 to suit the size of the wheel being operated on. As best shown in Fig. 5, the carriage 12 has a transversely-movable slide-17, mounted just under a cavity 12 in the carriage, this slide being movable by the action of a threaded rod or shaft 18, extending transpreviously affixed to the 5 versely in the carriage and having a handwheel'l9 to facilitate its rotation. 17 has an inclined upper surface, on which bears a block 20, longitudinally inclined and having an upwardly-projecting flange 21 of approximately semicircular form. The block 20 is intended to have the hub rested thereon, and the flange 21 serves to position the hub on the block, all of which is shown in Fig. 5. It is clear that by the adjustment of the slide 17 the block 20 may be'raised or lowered, and thus thewheel will be held at any elevation desired. On the outer end of the carriage an angled bar 22 is arranged, the vertical part of which is held to move vertically on the carriage and is provided with aof the hub.

26 indicates a center which serves to engage in the bore at the upper end of the hub, so as to hold the wheel in place and permitit to be turned as the operations of the machine require. This center is held on an arm 27, provided with a weight 28 and pivotally mounted on a slide 29, which works in aguide 30, formed on the horizontal portion of the beam 22, and which is provided with a device 31, by which to lock the slide 29 in any position desired. By these devices a wheel of any size may be properly fitted on the carriage'and held to turn around a constant axis.

The head-stock 11 is fixedly mounted on the base or frame 10 and carries revolubly a transversely-disposed shaft 32,to which movement is imparted from a drive shaft 33 through the medium of a friction or other clutch 34.. (See Fig. 2.) This clutch is operated by a troadle device .35, said parts 34 and 35 being of any preferred design. On the shaft 32 within the head-stock is fastened a cam 36, and this cam is designed to strike a The slide wear-piece 37, pivotally mounted on a collar 38, in turn fastened to the stem or shaft 39 of the hammer 40. The said wear-piece 37 engages at or near its free end with a cushion 41, of rubber or the equivalent, said cushion being set into a cavity in the collar 38. The cam 36 turns in the direction of the arrow shown in Fig. 3, striking said wear-piece, and this element being yieldingly mounted on the collar transmits to the same a cushioned movement. The hammer stem or shaft 39 is mounted to reciprocate longitudinally in the head-stock, the shaft being carried at one end in a box 42, fastened to the inner end of the head-stock, and at its outer end is a sleeve 43, which is threaded into a box 44, carried by the corresponding end of the headstock. The sleeve 43 is provided with a handwheel 45 to facilitate its rotation, and a handoperated lock-nut 46 is mounted on the sleeve outward from the box 44. By these devices 44, 45, and 46 the sleeve 43 may be moved to any longitudinal position desired with respect to the head-stock, and when properly adjusted this sleeve may be locked securely against further movement. An expansive spiral spring 47 encircles the shaft 39 and bears between the inner end of the sleeve 43 and collar 38, this spring tending to push the shaft 39 to the left in Fig. 3 and furnishing the impulsive force of the hammer. By adjusting the longitudinal position of the sleeve 43 the tension of the spring 47 may be regulated at will.

' 48 indicates a butter-spring which incloses the shaft 39 and bears between the spring 38 and box 42. It will accordingly be observed that as the cam 36 acts on the collar 38 and throws the shaft 39 to the right against the action of the spring 47 when the cam releases the collar the spring 47 will throw the shaft 39 and its hammer40 to theleft, delivering a blow upon the rim of the wheel, and as the cam continues this rotation it again moves the hammer to recover its stroke and again releases it to permit the spring 47 to throw the hammer onward.

49 indicates an arm which is pivoted intermediate its ends on abracket 10,formiug part of the frame 10, and to the upper end of which is connected a cord or chain 50, which runs over an idler-pulley 51, carried on the frame, and which has at itslower end a weight 52, serving to throw outward the upper end of thearm. Thearm 49 carries at its upper end a table 53, which is arranged to turn around a vertical axis and which has brackets 54 carrying the shaft 55 of a circular saw 56. This shaft 55 also carries a bandpulley 57, over which runs a band 58 down to a pulley 59, mounted on a shaft 60, revolubly carried in the lower end of the arm 49. Said shaft 60 also carries a pulley 61 or other device to facilitate the transmission of rotary movement to the shaft.

62 indicates a handle attached to the table 53 to facilitate moving the same around its axis independently of the movement of the arm 49. When the upper end of the arm 49 is thrown inward, it carries with it and places the saw in position to act on the rim of the wheel; but when the parts are in normal position under the action of the weight 52 the saw lies apart from the wheel and has no action thereon. It will be observed that the saw isdriven from the shaft 60 independently of any movement which might be performed by the arm 49.

The operation of the apparatus is as follows: The hubhaving the spokes driven therein is placed on the carriage in the manner described, and one of the rim sections is placed on the spokes and driven home by the action of the hammer 40. Let it be assumed that this section of the rim is indicated by the letter a in Figs. 1 and 2. When this has been done, the other section of the rim, (indicated by the letter 1),) is placed diametrically opposite the section a, with its ends overlapping the ends of the section a, and the spokes corresponding to the rim-section b are sprung upward to the line of said section and entered into the holes provided for the spokes. When this has been done, the slide 17 should be operated to lower the Wheel sufliciently to allow the hammer to Work against the rimsection b and the wheel should be manually turned to bring this rim section into line. The rim-section I) should be driven home onto its corresponding spokes. Then the arm 49 should be rocked forward against the action of the weight 52 and the saw 56 caused to cut off the ends of the rim-sections at the points indicated by the arrows c in Fig. 2. This allows the ends of the rim-sections to abut snugly together, and said sections will therefore spring toward each other, so as to lie in a plane, whereupon the wheel will be ready to have the rim finally fastened thereto and the tire applied.

Various changes in the form and details of my invention may be resorted to at will without departing from the spirit of my invention. Hence I consider myself entitled to all forms of the invention as may lie within the intent of my claims.
